Transmission Repair & Service Orillia, Ontario

Pinpointing the exact cause of any transmission problem takes skill, knowledge, and investigation

The evolution of transmissions has made these machines and systems increasingly complex. When transmission repairs are required, determining the cause and cure for what ails can be tricky. Why? Because transmissions have become remarkably complex and computerized and that presents both advantages and disadvantages. On one hand, transmission performance has become noticeably better in all vehicle makes and models. On the other, the increased complexity and digitization of transmission systems has made repair work a highly technical and complicated affair.


As you can imagine, there are different types of transmission repair jobs and options you can choose from depending on the nature of your vehicle’s breakdown. Understanding what those options are can help you make informed decisions when faced with a choice of transmission repairs to weigh.

A Repair for Every Type of Transmission Malfunction

Some transmission repair work is straightforward and mechanical in nature. Other times, it’s a combination of mechanical and electronic engineering that’s required to get your car back on the road. The most common types of repair work include:

  • Adjustments and in-car repairs. Most minor repairs are simple matters that are done without removing the transmission from the vehicle. If yours is a computer-controlled transmission that is not shifting properly, it is often the result of a computer sending incorrect signals due to a faulty sensor, or the transmission is not reacting to the command because of a bad connection or defective solenoid pack. If a non-computer controlled transmission is shifting too early or too late, it may require an adjustment to the throttle cable. If the vehicle has a vacuum modulator instead of a throttle cable, there is an adjustment that can be made using an adjustment screw in some designs. In vehicles with modulators, however, it is important to ensure there are no vacuum leaks and that the engine is running at peak efficiency.
  • Reseal jobs. A transmission is re-sealed to repair external transmission fluid leaks. If you see spots of red oil on the ground under the car, your transmission may need a re-seal job. To check a transmission for leaks, a technician will put the vehicle on a lift and examine the unit for signs of oil leaks. If a leak is spotted at any of the external seals or gaskets and the transmission otherwise performs well, the technician will most likely recommend that the transmission be re-sealed. Most of the external seals can be replaced while the transmission is still in the car but, if the front seal must be replaced, the transmission must first be removed from the vehicle to gain access to it.
  • Replacing accessible parts. There are a number of parts that are accessible without requiring the removal of the complete transmission. The parts that are accessible, however, vary from transmission to transmission and most transmission repair facilities would hesitate to provide meaningful warranties on external repairs for the simple reason that they cannot see if there are any additional internal problems in the components that are only accessible by transmission removal.
  • Complete overhauls. Also known as “rebuilding a transmission”, a complete overhaul involves the removal and disassembly of the transmission in its entirety. Every part is inspected for wear and damage, then cleaned in a special cleaning solution, or replaced with another part depending on its condition. Parts that have friction surfaces, such as bands and clutches are replaced as are all seals and gaskets. The torque converter is also replaced, usually with a remanufactured one. Technical service bulletins are checked to see if the auto manufacturer recommends any modifications to correct design defects that were discovered after the transmission was built. Automobile manufacturers often make upgrade kits available to transmission shops to resolve these design defects.

Replacing or Overhauling a Transmission

When a transmission requires an overhaul, there are two options that you may have. The first is to remove your existing transmission and overhaul it, then put the rebuilt unit back in your car. The second option is to replace your existing unit with another unit that has already been rebuilt or remanufactured.

A word to the wise: replacing your transmission with a used one may not be your best option. Used transmissions often have questionable histories that could create a whole new set of challenges. New transmissions, meanwhile, are mostly aftermarket transmissions billed as new but are in fact rebuilt transmissions with new parts.

The cost of the repair is always top-of-mind and understandably so. Transmission repairs are usually unexpected (and unwelcome). The cost varies depending on the outcome of our diagnostic testing, and we will help you to understand the various factors that come into play. We also offer our customers flexible payment options.

Whichever route you choose, you can trust our transmission experts to get you and your car back on the road.

Talk about service. Called 3 hours before closing time, was told bring truck by to look at transmission. So I arrived at 240pm on a friday, got my diagnosis,explained that my truck had gotten worse on the drive over to shop and I continued to explain how much I needed the truck in the following days to come for work. I was told that they would try to get the truck in before end of day and aim for me to get it back by Tuesday morning the latest if all parts are available. The work is not yet complete but on service this place is hands down best shop I've dealt with ever. Thanks mister transmission and crew for understanding my situation.

Came to Mr.Transmission to get a second opinion, not only were they more professional but respectful then the first place which I will not name. They worked with me and talked to me in terms that I understood and in the end my truck was fixed for a fraction of the price I was quoted. Thats the short version! These guys are Transmission Wizards and would recommend them to anyone.

Jim McHardy
My 2015 Murano is 6 months out of warranty an a 'transmission code' turned up. Nissan wanted money up front to look at it. Mr. Transmission Orillia was recommended and I had Chris assess it. He confirmed the code issue and flat out recommended I take the car to Nissan and work out something with them. At under 80,000kms, he said the warranty could be extended and I should try that process first. I am so impressed with the honesty and fairness I received by this company.Refreshing in today's world.If you have a transmission concern, I strongly suggest this company for a fair assessment.

Liz Freund
Christina is simply amazing. Not only is she very knowledgeable about all things transmission related, she remembers her customers' individual situations even when it's been months between visits - almost 2 years in my case! She's always pleasant and thorough over the phone and in person. The guys in the shop are clearly good at the work they do, but Christina really drives it home (pun intended) when it comes to providing an excellent customer-facing experience. Highly recommended!

Bjoern Ewald
Absolutely recommended! Hardworking, humble people who clearly know what they are doing. I wish every business was like that. Repaired the CVT on my 2014 Subaru and it runs like new. Price was reasonable. Glad I did not trade in the car at the dealership. Christina in the office sets a model of courtesy and professionalism, and the owner even drove me to the car rental after I dropped off the car. Can't say enough good things about these guys!

Just a shout out and 5 star review to a fellow Mr Transmission. I had the pleasure of meeting Chris a couple of weeks back and he helped me out a lot, he had parts that weren't available anywhere else in Canada! You couldn't be in better hands with Chris and Christina in Orillia. Thanks again. Kyle.
